Le Drian said French-built submarines, known for their long-range capabilities, would offer a strategic advantage over the rival bids. He also said the potential collaboration could prove mutually beneficial for both countries, fostering the exchange of new age, high-tech information that would “strengthen the industrial fabric” of Australia.

In February, Australian Foreign Minister Julie Bishop travelled to Tokyo to discuss the contract with his Japanese counterpart Fumio Kishida.

Bishop said Japanese officials were also keen to strengthen its alliance with Australia through the bid.

Japan has been frequently cited as the frontrunner to win the contract.

However, reports in the Australian media suggest the demotion of former Prime Minister Tony Abbott has helped France’s pitch as Abbott heavily favoured Japan’s bid.

A competitive process is under way with the winner set to be announced this year.
